Patent ES-454623-A1 (ES)
Title: Method and apparatus for combusting cabronaceous fuel
IPC: F23C6/04
Filed: 1976-12-28
Abstract: To ensure that the process is flexible with respect to the fuels which can be used and that also the utilisation of, for example, sulphur-containing fuels is possible, the process operates as follows: A first mixture (18) of carbonaceous fuel (10) and air (14) is burned in the presence of a catalyst (25) under at least approximately adiabatic conditions. The catalyst (25) operates at a temperature which is above the instantaneous auto-ignition temperature of the first mixture (18) but below a temperature at which a noticeable formation of nitrogen oxides would take place. The waste gas from this combustion is mixed with a fuel-containing component (32) other than the first mixture (18), and the mixture (40) is homogeneously burned in order to produce a waste gas (50) which can be used as an energy source. The fuel in the said fuel-containing component (32) can - in contrast to the fuel (10) in the first mixture (18) - also be a fuel which would poison the catalyst and/or which is difficult to vaporise and to mix with air. The process is intended especially for producing a hot waste gas for use as a heat source (for example in an oven) or as an energy source (for example in a turbine installation).

The calibration mechanism (10) includes a support bracket (20) mounted on the switch (12) and a cam assembly including an integrally formed cam member (16) and a camshaft (18). A plunger adjustment mechanism includes a pivotally mounted lever (14) having a cam follower (42) in following engagement with the cam (16). The support bracket (20) defines a bore (50) adapted to receive the camshaft (18).

Title: Extracellular microbial lipoheteropolysaccharides and derivatives, their preparation and compositions containing them, and their uses.
IPC: C09K23/00
Filed: 1981-03-02
Abstract: Growth of Acinetobacter Sp. ATCC 31012 on various substrates and under varying conditions has been used to produce two classes of extracellular microbial protein-associated lipopolysaccharides (the "emulsans") which, on a weight-for-weight basis, are probably the most efficient emulsifiers discovered and which possess certain characteristics that permit these unique extracellular microbial lipopolysaccharides to be widely used in cleaning oil-contaminated vessels, oil spill management, and enhanced oil recovery by chemical flooding. These classes have been named alpha -emulsans and beta -emulsans, both of which have substantially the same polymer backbone but differ from each other in certain important structural aspects. Deproteinization of emulsans by hot phenol extraction produces the lipopolysaccharide components (the "apoemulsans") of each of such th emulsans, which components have been shown to be completely N-acylated and partially O-acylated heteropolysaccharides made up of a major amounts of D-galactosamine and an aminouronic acid, the O-lipoacyl portions of such apoemulsans containing varying percentages of fatty acid esters in which the fatty acids contain from about 10 to about 18 carbon atoms. Base hydrolysis under mild conditions of the emulsans and apoemulsans produces derivatives (the " psi -emulsans" and apo- psi -emulsans", respectively) which are completely N-acylated and partially to completely O-deacylated. Base hydrolysis under strong conditions of any of these products produces another derivate (the "proemulsans") which is completely O-deacylated and is partially H-deacylated. Emulsans and apoemulsans, both of which biopolymers are strongly anionic, exhibit a high degree of specificity in the emulsification of hydrocarbon substrates which contain both aliphatic and cyclic components. In addition, these extracellular microbial polysaccharides as well as their O-deacylated and N-deacylated derivatives are adsorbed on and capable of flocculating aluminosilicate ion-exchangers, such as kaolin and bentonite.

Title: Process for the purification of hexamethyl disiloxane, and azeotropic mixtures used in this process.
IPC: C07F7/20
Filed: 1982-03-04
Abstract: Process for purifying hexamethyldisiloxane contaminated with toluene or other solvents that cannot be completely separated from the hexamethyldisiloxane by distillation, based on the discovery that hexamethyldisiloxane forms a previously unknown azeotrope with acetonitrile. This azeotrope has a heavier phase that is rich in acetonitrile and a lighter phase that is rich in hexamethyldisiloxane. These phases are mutually immiscible. The azeotrope starts to boil at 71.4 DEG C., which permits the hexamethyldisiloxane to be separated at relatively low temperatures from the impurities. The process involves one or more entrainment distillations in the presence of an excess of acetonitrile and the re-separation of the acetonitrile from the resulting lighter phase by distillation. Two further novel azeotropic systems, one consisting of hexamethyldisiloxane and toluene and the other of acetonitrile and toluene, are provided.
